IMPROVEMENT IN SAD-IRONS.

Specification forming part of Letters Patent No. 205,352, dated June 25,1878 application filed I May 8, 1878.

description of the invention, such as will en-- able others skilled inthe art to which it pertains to make and use it, reference being had tothe accompanying drawings, which form part of this specification, inwhich- Figures 1 and 2 are longitudinal vertical sections.

The primary object of my invention is to provide an iron which will becomparatively inexpensive, and from which, when in use, the radiation ofheat upwardly toward the handle will be prevented.

My invention accordingly consists in the combination, with an ironhaving a dead-air space and a detachable metallic cap, of a lining ofasbestus, forming a ceiling to said dead-air space and a non-conductingjoint between the body and cap; also, in the specific construction,combination, and arrangement of parts, as hereinafter described andclaimed.

Referring to the accompanying drawing, A is the body of the iron, casthollow with upright walls aa,which inclose a dead-air space or chamber,a. A is a central elevation or post rising from the bottom of saidchamber a B is a detachable metallic cap for the chamber a and G is alining of asbestus, forming a ceiling for the chamber a.

I) is the handle, composed of the wooden hand-piece d secured tometallic standards (1 by screws d which enter its ends, as shown in Fig.1, or by a rod, d extending all the way through said handle, as seen inFig. 2.

The standards (1 are bent to form feet 61 which rest upon washers binterposed between. said feet and the cap B, said washers being ofasbestus or other nonconductin g material.

E E are screws, which pass through the feet at, cap B, lining O, andchamber a to threaded openings a in the floor of said chamber. Thescrews E E accordingly serve not only to retain the cap B in its placeon the body A, but also to secure the handle-standards to said cap.Non-conducting washers b are also fitted'on the screws E between theirheads'e and the feet d.

Air being a poor conductor of heat, the chamber a will serve to hinderthe too free radiation of caloric from the bottom of the body Aupwardly, while the asbestusceiling C will absolutely prevent thetransmission of heat through it, and will thereby protect the operatorshand from discomfort.

The washers b b will prevent the heat of the iron from being conductedto the handle standards through the screws E. The asbestos lining Grests upon' the upright walls of the body, and between the same and thecap B, thus forming a tight non-conducting joint, and is supportedcentrally against said cap by the central post A.

The bottom a itwill be noted, is made of considerable thickness, so asto retain heat for a long time, the iron being designed to be heated bybeing placed upon the stove or range in the manner of a common flat orsad iron, and therein differs from hollow irons consisting of thinshells heated by means of slugs or cores introduced into theirinteriors, the bottoms of said shells being of very slight thickness, soas to permit the free outward or downward transmission of heat.

What I claim as my invention is 1. In combination with an iron, A,having a dead-air space or chamber, a, and a detachable metallic cap, B,a lining of asbestus, O, forming a ceiling to said air-chamber, and anon-conducting joint between the body and cap, substantially as shownand described.

2. The combination of iron A, having airchamber a and central post A,detachable cap B, asbcstus lining O, handle D, screws E E, and washers,substantially as shown and described.

In testimony that I claim the foregoing I have hereunto set my hand this4th day of May, 1878.
